This text examines the definition of philosophy and emphasizes the necessity of distinguishing between "true" philosophy (orthé filosofía) and its false or apparent forms. The author argues that a definition based solely on the external appearance of philosophical activity is insufficient for identifying its true nature. Since philosophy is fundamentally an act of thought, its essential form remains inaccessible from the outside unless it is expressed or formulated. The process of understanding these expressions is likened to decoding, which requires an initial assumption that a deeper meaning exists. If one approaches the plurality of philosophies merely by describing their external features without seeking intrinsic significance, it becomes impossible to differentiate between authentic philosophy and pseudo-philosophy. The text calls for an active interpretative approach that moves beyond superficial observation to uncover the meaning hidden within signs and sounds. Ultimately, identifying true philosophy requires a willingness to engage with the internal logic of thought, rather than being misled by its externalized representations or simply accepting a diversity of opinions without critical evaluation.
